I will be in Dublin for 4 days in July. As we were there last summer for 3 days, I have seen some of the musts and feel like this time we will have time for a day trip to Dublin's outskirts. We will not be renting a car so need to rely on public transportation...
I was looking at Dalkey, Powerscourt, Howth etc.
Any recommendations? We would like pretty scenery, maybe some hiking... we are pretty open
Thank you!
